Specification of Letters Patent.

Patented June 3, 'l 913.

Original application filed August 31, 1911, Serial No.646,993. Divided and this application led November 20, 1912. Serial No. 732,399.

To all whom may concern -Be it known that I, SAMUEL HMS, a citizen of the United States of America, residing in New York, in the borough of Manhattan, county and Stateot New York, have invented certain new and useful Improvements in Spool-Racks, of which the following =is a specification.

This invention relates to spool-racks, and more particularly to spool-racks of that class in which means are provided for prevent-ing the unauthorized removal of spools from t-he rack; and for this purpose the invention consists of a spool-rack which comprises a spool-supporting plate having spindles supported thereon for the spools, standards for supporting said plate, thread-guiding plates which are pivoted at their outer ends and provided at their inner ends each with a semicircular recess and flange, and clamping means inclosing said flanges for locking the thread-guiding plates into position on the center standard.

The invention consists further of certain details yof construction which will be fully described'hereinafter and tinally pointed out in the claims.

In the accompanying drawing, Figure 1 represents a side-elevation, partly in section, of my improved spool-rack, showing the spools arranged in staggered relation to each other on an elongated supporting A frame, Fig. 2 is a plan-view of Fig. 1, Fig.

3 is a detail-view showing the ends of-the thread-guiding plates placed adjacent to each other, Fig. 4 is a detail vertical section, on line 4, 4, Fig. 3, showing the ends of the thread-guide plates held in position by the clamping means, Fig. 5 is a detail'section of the spindle, showing a brake-device for the lspool applied to the spindle and, Fig. 6 is a horizontal section on. line G, 6, Fig. 5, showing the recess in the spool-supporting spindle.

Similar reference characters indicate corresponding parts throughout the several figures of the drawing.

Referring to the drawing, a represents a spool-supporting plate, which is made of oblong, undulating or other form, and provided with a number of upright spool-supporting spindles Z), which are preferably arranged in staggered relation to each other throughout the support-ing plate a. The supporting plate a rests on collars el of the standards e, which latter are attached at their base to the supl'iorting base-plate c2 of the spool-rack. At the upper ends of the standards o are arranged collars o on which rest the outer ends of two thread-guiding plates (Z which are pivoted to the upper ends of the outer' standards said flanges being provided with raised lugs or projections c" for preventing the removalV of the thread-guiding plates '(Z fromthe upper ends of the standard c, and yet permit the thread-guidingl plates to be moved pivotally around the end of the standard e into the position shown in dotted lines in Fig. 2. The inner ends of the plates (l are provided with recesses l1 having each a raised rim or flange di around said recess, each of the plates having a similar-shaped end, so that when their inner ends are placed together around the middle standard c they form a circular' opening around the same. The upper end of the middle standard c is screw-threaded at the portion above the rimmed inner ends of the threadguiding plates d for engagement with an interiorly-threaded clamping thumbscrew cl3. The thumb-screw d extends at its lower end below the screw-threaded portion and embraces both semi-circular rims (Z2 when the thumb-screw is screwed downwardly, and clamps the ends of the threadguiding plates firmly in position for preventing their removal. The thread-guiding plates (l are supported above the upper ends of the spindles Z) at such a distance trom the same that it. is impossible to remove any one of the spools placed on the spindle, whether they are large or small. In order to secure the clamping thumb-screw d in position, the hasp el of a pad-lock e is passed through a diametrical hole et' in the upper end of the middle standard c so as to prevent the unscrewing of the thumb-screw, when the padlock is locked to the standard, by any one not authorized to open the same. In order to prevent the detaching of the thumb-nut d from the middle standard c when the lock is removed, the upper end of the standard c above the hole e2 is provided with a transverse stop-pin e3 so that the thumb-screw cannot be raised to such an extent as to get detached from the standard and be mislaid and lost. When it is desired to open the thread-guiding plates d, the thumb-nut is raised sutlicient-ly so that its lower end clears the endsl of the thread-guiding plates (Z and permits them to open sidewise as shown in dotted lines in Fig. 2, so that the spools can be placed in position on their spindles. The thread-guiding plates Z are then returned into position in line with each other, and clamped by the thumb-nut and securely held by replacing the padlock. l

lIn the spool-rack described, 1n place of one large spool, two spools of different sizes, and likewise different colors and thicknesses of thread, may be arranged on the spindles b. The smaller spools are arranged one on top of the other, the upper spool being freely turnable on its spindle Z) While its thread passes through the guide-openings in the thread-guiding plates d. The pull on the threads as they are used by the operators permits thc ready unwinding of the spool. In o-rder to enable the lower spool to be used independently of the upper spool and to prevent the too free unwinding of the same, a braking device is provided which consists of a flat spring f attached to the lower-end of each spindle b and bent slightly away from the same While its upper end is seated in a recess b1 of the same as shown in Fig. 5. Vhen a spool is placed on one of the spindles b the spring f'binds on the inner central portion of the spool so as to exert a frietional brake-action on the same, by which brake-action the lower spools are unive-und directly Without passing through one of the openings in one of the threadguiding plates, the braking action being such as to prevent the too quick unwinding of the threads and thereby any entanglement with other threads.

The improved spool-rack prevents the unauthorized removal of the spools, While it is of great convenience to the operators as a number of them can be readily supplied with the threads required while they are sitting around a table on which the improved spool-rack is supported at a proper elevation.

l claim:

1. A spool-rack,

comprising upright l standards, a spool-supporting plate supported thereon, spindles supported on said plate, threadaguiding plates above the spindles, pivoted to the standards at their outer ends, said plates being provided at their inner ends with a semicircular recess having a rim, and clamping means inclosing the rims on the inner ends forv clamping the threadguiding plates in position.

2. A spool-rack, comprising' supporting standards, a -spoolsupporting plate, spindles supported on the same, thread-guiding plates pivoted at their outer ends to the upper ends of the standards, collars on said standards for supporting the spool-supporting and thread-guiding plates, said thread-t guiding plates having rimmed semicircular recesses at their inner ends, and clamping means inclosing said rimmed ends for retaining the thread-guiding plates in position. 3. A spool-rack, comprising supporting standards arranged in line with each other and provided with collars, a spoolsupporting plate supported on the lower collars of the standards, thread-guiding plates supported at the upper ends of said standards, said thread-guiding plates being provided with openings for the threads and pivoted at their outer ends to the outer standards and provided at their inner ends with rimmed semicircular recesses, and a clamping screw-nut binding on the rimmed inner ends of said thread-guiding plates, said screw-nut being adjusted on the threaded portion of the middle standard.

4. A "spool-rack, comprising upright supporting st-andards having collars at different points of their height, a spool-supporting plate supported on the lower flanges of the standards, spindles supported on said plate, thread-guiding plates supported on. the upper flanges of the standards and pivoted at their outer ends to the same, the inner endsv of said thread-guiding plates be- 'ing provided with rimmed semicircular recesses fitting aroundvthe middle standard, a. thumb-screw turning on the upper threaded end of the middle standard and provided With a downward extension for binding on the rimmed inner ends of the thread-guid' .ing plates, and a stop-pin at the upper end of the middle standard for preventing the detaching of the thumb-screw.

In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
